Final answer:
The next term in the geometric sequence is -6.75.
Step-by-step explanation:
This is a geometric sequence, where each term is found by multiplying the previous term by a constant ratio.
To find the ratio, we can divide any term by its previous term. Let's use the first two terms:
Ratio = -3 / 2 = -1.5
Now, to find the next term, we can multiply the last term by the ratio:
4.5 * -1.5 = -6.75
Therefore, the next term in the geometric sequence is -6.75.
